Description
The present invention generally relates to toilets for vehicles and, more particularly, to an apparatus and method for a toilet for vehicles wherein the toilet is an integral part of a functional passenger seat having multiple uses. The toilet of the present invention is basically comprised of a passenger vehicle seat, a toilet bowl, a modified seat cushion, a water supply, a waste system and a seat swivel mechanism. The toilet is functionally integrated with a vehicle passenger seat in a van, recreational vehicle or cross country truck and allows the seat to be used in multiple orientations for a variety of seating arrangements.
Vehicles are supplied with toilets to enable its passengers to travel long distances without leaving the vehicle, to avoid having to use public restrooms, to provide accessible private toilet facilities for handicapped travellers, and to provide toilet facilities in remote geographical areas. Vehicles have limited interior space and interior toilet apparatuses must be space efficient. Further, modern travel conditions require that any mobile toilet apparatus retain waste for disposal at an appropriate site.
Prior art reveals other toilet apparatuses for vehicles. U.S. Pat. No. 1,359,544 describes a toilet device for automobiles. A commode structure is located between the front and rear seats and is hinged so that, when not in use, the structure is lowered beneath the floor of the automobiles.
Another apparatus is described in U.S. Pat. No. 1,454,618. A combined commode and lavatory device consisting of depended basins is installed in a fixed automobile seat, with the various openings and cavities concealed by removable seat cushions.
U.S. Pat. No. 1,569,571 provides a toilet apparatus when an automobile seat is temporarily removed. The apparatus consists of an orifice in the floor of the vehicle covered by hinged doors. The doors swing up to support a toilet seat hinged to the side of the vehicle. The toilet systems taught by the prior art do not provide a passenger seat adapted with a toilet system which is self contained beneath an easily removable seat cushion and which is adapted to provide a sanitary toilet system having a water supply and a waste holding tank. Consequently, a need exists for a toilet apparatus for vehicles which is integrated with a passenger seat so as to require no space in the vehicle beyond that occupied by a regular seat, does not require removal of seats or seat sections, contains holding tanks while providing a seal against odor and splashing liquids, and provides for multiple positioned uses of the passenger seat within the vehicle.
The present invention provides an apparatus and a method for installation of a toilet in a vehicle so that the toilet is integrated with the structure of a rotatable vehicle seat, requires no additional space within the vehicle, and provides for sanitary collection of waste materials. The apparatus of the present invention consists of a modified passenger seat, a toilet which is structurally integrated with the seat, a water supply system, a waste system and a swivel mechanism. The method consists of providing a toilet structurally integrated with a passenger seat, modifying the vehicle to provide a water supply and a waste system, installing the toilet apparatus within the vehicle, and using the toilet apparatus.
